GuitarMidi-lv2 now has a build option WITH_AUDIO_OUTPUT which you can
activate to output short blips on the onsets. My measurements show a
latency of 4ms for the high open e (330Hz) and 16ms for the low E
(82Hz). The higher the note, the lower the latency.
This means for higher funk chords and solos it is absolutely realtime.
As with the low notes the 16ms I think I can improve the situation by
training the model on partial waveforms.=20
What do you think?
